GLOBE I-IOLDER.

Application filed January 16, 1913.

To all whom it may concern Be it known that I, JOHN KIRBY, J r., acitizen of the United States, residing in the city of Dayton, in thecounty of Montgomery and State of Ohio, have invented certain new anduseful Improvements in Globe- Holders for Gas and Electric-LightFixtures; andI do hereby declare the following to be a full, clear, andexact description of the same, reference being had to the accompanyingdrawings, and to the referencenumerals marked thereon, which form a partof this specification.

My invent-ion while being particularly applicable to lighting fixturesfor use in railway cars is also applicable to lighting fixtures forother uses; and its object is to com bine with such fixtures a holderfor the shades or globes used in connection therewith, which will beefficient, durable and of simple construction and which will support theglobe rigidly in place and be sufficiently elastic or yielding toprevent rattling or breaking under the jars and vibrations incident tomoving cars or vehicles; and it conteinplates the performance of saidfunction without other assisting means of support for the shade orglobe.

The invention consists in certain new and novel combination of elements,which will be hereinafter fully described and claimed.

In the said drawings Figure 1 represents a side elevation of. thefixture provided with dual releasing means and a shade held in positionin the holder, a portion of both being broken away showing the assembledparts in section. Fig. 2 is a sectional plan view of the fixture andshade below the line or an in Fig. 1, the spring, however, being shownin full. Fig. 3 is a broken side view of the outer casing of the fixtureshowing the same partly in section with the helical spring mountedtherein, and also showing a modification of the releasing means shown inFig. l, the helical spring being shown in a released or expandedposition. Fig. 4 is a broken perspective view showing the samemodification as in Fig. 3, the helical spring being shown in acontracted or holding position. Fig. 5 is a perspective view of thespring holder removed from the casing. Figs. 6 and 7 show modificationsin the flexible holder.

Similar reference numerals indicate corresponding parts in all thefigures. of the drawings, in Fig. 1 of which drawings I haveSpeeificationof Letters Patent.

shown the fixture provided with a base plate 1 by which it may besecured to the deckrail of a car or to any suitable supporting surface,but as the invention relates only to the means for holding the shade orglobe in position the method of its attachment to any particular supportis immaterial and may be varied to suit requirements.

2 is an annular outer casing, preferably semi-circular in crosssections, which may be made of either cast or sheet metal, it isprovided with an interior groove or channel 3 and a central opening 4.to receive the shade 5. Located within the channel 3 and extendingsubstantially therearound is a helical annular spriiig 6 which, when itsends are drawn to a predetermined distance, forms an opening of lessdiameter than the said opening t in the casing 2, through which acorrespondingly grooved neck 7 of the shade 5 passes, so that when theshade is in its proper place in the holder the spring 6 engages thegrooved neck 7 and holds the shade firm, yet with sufficient elasticityto prevent its breaking, from causes such as shocks and vibrationincident to a moving vehicle. The normal tendency of the spring 6 istoward a straight line and the diameter and size of the channel 3 issufiicient to permit of its expansion in that direction until thecentral opening, formed by said spring, is large enough to permit theneck of the shade to pass freely therethrough. lVithin the coils of thespring 6 there is preferably placed a piece of rubber, asbestos or otherflexible material 8, the diameter of which may be somewhat less than thebore of said spring, and longitudinally through this piece of materialthere passes a spring wire 9 formed to comprise a part of a circle orring of larger diameter than the said opening 4 so that when confinedwithin the said channel its tendency will be to open out to its normalshape or position. The ends of this wire 9, extend. beyond the ends ofthe spring 6 and are bent outwardly, as shown at 1011, one of theseoutwardly bent ends may pass through the wall of the casing and besecured thereto and the other may be adapted to operate in a slot 12, asshown in Figs. 3 and 4, or both ends may be free to operate in slots1213, as shown in Figs. 1 and 2. The ends 1011 of the wire 9 arepreferably provided with knobs 14, which serve as easy finger pieceswith which to manipulate the holder. The slots 1213 are formed in thewall of the casing longitudinally with the channel 3 and their innerends open into downwardly extending slots or pockets 1516 adapted toretain the ends of the wire ring 9 in a contracted position, so that theinner surface or diameter of the coil spring 6 will engage the neck 7 ofthe shade 5 and hold the latter in place. Thus when a shade is to beremoved from or in serted in the holder one or both of the ends of thewire ring 9 as the case may be, are raised from its Or their lodgment inthe slots 15 or 16, or both, and the outward tension of the spring 6 andwire 9 will force the ends lO11, one or both, to move in the slot orslots 1213 until the limit of travel is reached when the neck of theshade will be free to pass through the enlarged opening caused thereby.

In the foregoing description of my invention I have described what to meseems to be the most approved manner of constructing the same. But itwill be apparent to those familiar with the art to which the inventionappertains, that the details of construction as hereinbefo-re given canbe deviated from without departing from the spirit of the invention, as,for example, the use of the flexible lining 8 may be omitted as shown inFig. 7, or both the flexible lining 8 and the wire ring 9 may be omittedand the finger pieces 14 attached directly to the ends of the spring 6,as shown in Fig. 6, and various other modifications may be made andstill keep within the scope of the invention. Therefore, I do not Wishto limit the invention to the exact details of construction which I haveshown and described.

Having thus fully described my invention, I claim In a shade holder ofthe character described, the combination of a casing having an interiorannular channel and a central opening, a helical annularly disposedspring located in said channel and extending substantially therearoundadapted to engage the neck-portion of a shade, and means operativethrough openings in the wall of the casing whereby the said helicalspring may be permitted to expand to release the shade or contracted tograsp and hold the same securely in its place in the holder at the willof the manipulator.

In testimony whereof, I hereunto subscribe my name this 14th day of January, 1913.
